BRUSH DEVICE FOR CLEANINGIBOLTING-CYLOTIH':

SPECIFICATION forming part of Letters Patent No. 733,858, dated July 14:, 1903. Application filed March 24,1902. Serial No. 99,686. (No model.)

To all whom it may concern:

Be it known that I, CHARLES WILLIAM MANN, a citizen of the United States, and a resident of Greenville, in the county of Greenville and State of South Carolina, have invented a new and Improved Brush Device for Cleaning Bolting-Oloth, of which the following is a full, clear, and exact description.

My invention relates to a device for cleaning bolting-cloths or gyratory sieves used in fiouring-mills 5 and the purpose'of' the inven: tion is to provide a brush which is made to travel with a circular motion in engagement with the bolting-cloth, movement being im-. parted to the brush through the gyratory movement of the bolting-machine, and also to provide means whereby the brush will be compelled to take a course parallel with and at each side of a line drawn horizontally through a portion of the center and a course parallel with the ends of the frame,an d means whereby the brush is prevented from moving backward.

A further purpose of the invention is to provide a brush having a circular body pro.- vided with a cleaning material and a main brush weighted at one end and mounted to turn upon the body.

The invention consists in the novel (3on struotion and combination of the several parts, as will be hereinafter fully. set forth, and pointed out in the claims.

Reference is to be had to the accompanying in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a longitudinal section through the bolting-frame and through the brush, the section being taken practically on the line 1 1 of Fig. 2. Fig. 2 is a horizontal section through the bolting-frame, taken practically on the line 2 2 of Fig. 1. Fig. 3 is an enlarged vertical section through the brush. Fig. etis a plan view of the main or revolving section of the brush and its weight, and Fig. 5 is a perspective view of the brushing surface adapted at times as a substitute forthe tufts shown in the other views.

A represents a portion of the frame of the machine, and B a bolting-frame, which is provided with an upper bolting-surface 10,of mohair, cloth, or other suitable material, and a bottom surface 11, of a reticulated or perforated material, spaced from the bolting-cloth and prevented from sagging by transverse brace-straps 12. a

At the central longitudinal portion of the upper surface 11 a partition 13 is secured, extending-nearly to the bolting-cloth 10; but the partition does not extend to the ends of the bolting-frame, ample space being provided between the ends of the partition and the ends of the bolting-frame for the free-passage of a brush 0, which is loosely placed between the upper and lower surfaces of the boltingframe. The bolting-frame is given its gyratory movement in the usual manner.

The cleaning-surface of the brush 0 is in contact with'the under faoe'of the boltingcloth and through the motion ofthe boltingframe travels around the partition 13, and the middlings from the wheat pass over the bolt ing-cloth in the usual manner and the flour is sifted through the cloth as the middlings are forced along by the motion of the boltingframe, and the movement of the brush below and in engagement with the bolting-cloth keeps the meshes of the same open at all times for the free passage of the flour.

Stops 17 are secured upon the bottom re-" ticulated or perforated section 11 of the bolting-frame. These stops are arranged at intervals apart in lines parallel with the partition 13 and atright angles to the partition between the ends of the partition and the ends of the bolting-frame, as is best shown in Fig. 2. These stops 17 may be made of strap metal or maybe made of wire, and one end of each strap'is attached to the perforated or reticulated surface 10 and extends upward at an angle in direction of the delivery end of the bolting-frame, as is shown in Fig. 1, andis then carried down through the frame, forming a vertical shoulder 17 at each stop facing the delivery end of the bolting-frame. material of each stop'is then preferably carried horizontally beneath the reticulated or The perforated surface 11 of the bolting-frame also ward, but will be effectually prevented. from moving in a rearward direction. I desire it to be understood that the upper and end portions of the partition 13 may be covered with leather, felt, or other soft material, so as not toinjure the brush norinjure the bolting-cloth with which the partition may be brought in substantially close engagement.

The brush 0 consists, preferably, of a circnlar body-plate 18, having openings 19 produced therein, and preferably the said bodyplate 18 is dished, its upper surface being more or less convexed, and at the upper marginal portion of the body-plate 18 a'ring 20, of leather, rubber, or like material, is secured in any suitable or approved manner, extending beyond the edge of the body-plate 18, so that the said body-plate will not injure any portion of the bolting-frame with which it may come in contact, and in the said ring 20 tufts 21, of drawn mohair or other suitable material, are secured, adapted to extend upward sufficiently to engage with the under face of the bolting-cloth 10 when the brush is in use.

In connection with the body-section of the brush just described a main section C is employed, which section is adapted to perform the major portion of the cleaning. section 0' is adapted to turn upon the upper face of the body-plate 18 within the ring 20, and the said main or revolving section 0 of the brush preferably consists of a leather or rubber back 22, in which tuft-s 23 of drawn mohair or like material are secured at or near the margin. A stay-plate 24 is fitted upon the upper surface of the back 22, between the rows of tufts, as is shown in Figs. 3 and 4, and this stay-plate is secured to the back 22 by rivets or other suitable means.

Apivot-bol't- 25 is passed from below through the central portion of the body-plate 18 and loosely through the back 22 and stay'plate 24 of the revolving section of the brush, being provided at its upper end with a suitable nut and Washer 26, below the upper surfaces of the tufts in the brush.

A weight 27 is secured to the bottom of the main rotary section 0 of the brush at one end, and this weight is preferably provided with wings 27", which extend beyond opposite sides of the body of the said rotary sec tion of the brush, and the bottom of the weight is so shaped that the main rotary section C of the brush will turn horizontally or in a line parallel with the under face of the bolting-cloth 10, so that its tufts 23 will engage equally with the surface of the bolting-cloth with which they may be brought'in contact.

When the bolting-cloth is exceedingly fine, the tufts described in connection with the brush may be omitted, especially the tufts 23, carried by the main rotary section 0 of the brush, and a pad 28 be substituted, (shown in detail in Fig. 5,) which pad may be made up of fabric, being provided with a suitable back 29 and a pile upper face 30. For ex- This main ample, the material employed may be such as is used in moquette, velvet, or Axminster carpet.

Any desired number of brushes may be employed, and where very little brushing is necessary the main revolving section C of a brush may be removed, and the weight 27 in this event is fastened at the central portion of the body-plate 18. It will be observed that the brush travels beneath the bolting-cloth on the reticulated or perforated screen moved by the motion of the bolting-machine and will continue to travel as long as the machine will give it motion, and the flour finds a ready exit through the said reticulated or perforated screen. The weighted brush travels with the same speed as the moving parts of the bolting-machine, and while the body of the brush has a circular movement when the boltingmachine is in motion the section C has an independent circular movement accelerated by the attached weight 27.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a bolting-machine, a bolting-frame provided with a bolting-surface and a perforated or reticulated screen, and a brush mounted to travel on the screen in engagement with the bolting-surface, the said brush comprising a body-section, and a weighted main section pivoted to the central portion of the body-section and arranged to revolve thereon as described.

2. In a bolting-machine, a bolting-frame provided with an upper bolting-surface and a lower reticulated or perforated surface, a brush having free movement between the upper and lowersurfaces of the frame and moved by the movement of the machine, the said brush having a bod y-section and a weighted section mounted to revolve on the body-section, and stops on the reticulated surface of the frame, compelling the brush to travel in one direction, the said stops inclining upward from the reticulated surface in direction of the delivery end of the bolting-frame and each having a vertical shoulder facing the said delivery end of the frame, substantially as described.

3. In a bolting-machine, a bolting-frame provided with an upper bolting-surface and a lower perforated or reticulated screen, and a brush mounted to travel in the screen in engagement with the bolting-surface, the motion of the machine imparting motion to the brush, which brush consists of abody-section provided with brush material at its margin, and a weighted main section mounted to revolve upon the body-section within the line of the brushing material carried thereby, as and for the purpose specified.

4. In a bolting-machine, a bolting-frame provided with an upper bolting-surface, a lower perforated or reticulated screen, a central partition secured to the screen, stops around the said partition, and a brush mounted to travel on the screen'in engagement with the stops and in engagement with the bolting-surface of the frame, the motion of the machine imparting motion to the brush, which brush consists of a perforated body-plate provided with a marginal ring of yielding material on its upper surface, tufts of brushing material carried by the said ring, and a main section having an upper brush-surfaceand pivoted to the central portion of the baseplate, and a weight attached to one end of the main section of the brush, as and for the purpose set forth.

5. In a bolting-machine, a cleaning-brush consisting of a circular body-plate having tufts of brushing material extending upwardly from the marginal portion thereof, and a main section mounted to revolve on the body-plate, which main section is provided with a brushing material adjacent to its martherefrom, and a main brush-section mounted to revolve on the body-plate and also provided with brushing material, the said main brushsection having a weight at one end, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

CHARLES WILLIAM MANN.
